Crane Darning's double-suction, horizontal split-case centrifugal pump combines the latest in hydraulic design with almost a century of application experience to meet today's industrial and municipal requirements.

Deming split-case pumps offer longer life, higher efficiencies, less downtime and lower maintenance costs. Maximum interchangeability of standardized parts simplifies design.

Heavy fabricated-steel bases, including drip-lip type, are available to mount the pump and driver. Flexible shaft coupling connects driver to pump.

Standard-design pump can be vertically mounted with grease lubricated bearings and mechanical shaft seal. Vertical units require minimum floor space, offer in-line piping arrangement and provide greater motor protection in potential flooding areas.

Design Features

N/A

    1. Compact design - Heavy shaft and short bearing span reduce shaft deflection to a minimum, providing longer packing and hearing life, lower maintenance costs. Requires less floor space. Clockwise rotation standard; counterclockwise rotation optional.
    2. Casing - Horizontally split, upper and lower half bolted and doweled to provide perfect alignment. Bearing supports are cast and bored integrally with lower-half casing. Upper half easily removed for inspection of complete rotating assembly without disturbing bearings or alignment. Flanged suction and discharge connections are located in the lower-half casing, permitting inspection and maintenance without disturbing piping or drive alignment. Flanges are 125# ANSI standard; 250# ANSI flanges optional.
    3. Impeller - Enclosed, double-suction type. Cast in one-piece and balanced to minimize thrust and to ensure longer bearing life, smooth operation. Keyed to shaft and locked in position by threaded shaft sleeves.
    4. Wearing rings - Close running clearance minimizes pressure leakage between suction and discharge chambers of the casing. Easily replaceable. Casing rings standard on all sizes. Impeller rings standard on 8" and larger sizes, optional on smaller sizes.
    5. Shaft sleeve - Protects the shaft against corrosion and wear, extends through gland for maximum shaft protection. Threaded against impeller hub to tighten with rotation, yet free for thermal expansion with temperature changes.
    6. Shaft - Large-diameter, precision- machined, high-strength steel shaft provides maximum strength with minimum shaft deflection. Double extended shaft available for auxiliary drive requirements. Three-year warranty on shaft breakage.
    7. Bearings - Cartridge-mounted to permit removal without disturbing upper- or lower- half casings. Outboard bearing is double-row type, accepting radial and thrust loads. Inboard bearing is single-row, accepting shaft radial load, and is free to move axially in housing to compensate for shaft expansion due to temperature changes. Dual lip seals exclude dirt and moisture. Grease or oil lubrication available.
    8. Stuffing box/mechanical seal - Stuffing box is extra deep to accept minimum of five rings of packing and lantern ring. Internally drilled liquid passage in upper-half casing provides lubrication to the packing area. External lubrication, such as oil under pressure, may be connected to upper-half casing. Grease lubrication optional. Heavy split gland facilitates maintenance. Wide choice of mechanical seals available.
